what is the slump value for M20 concrete
According to IS 456-2000 the value is square root of 5700fck
Concrete does not have a very good insulating value, and neither does steel. The mixture of the two will add structural stability to what you are building, but it (commonly) will not enhance the concrete's insulating value.

what is the slump value for M20 concrete
since k=E/3(1-2n): where k=bulk modulus and n=poision's ratio it can be seen that value of poision's ratio can't be smaller than 0.5 in order to keep k be +ve.hence poision's ratio is 0.5
According to IS 456-2000 the value is square root of 5700fck

There is no constant value for the ratio of the rebars and concrete volume. The rebars depends on the structural designer's safety factor and the factors affecting the framing like wind, earthquake and soil.
The value of a ratio is the total
There is not a ratio that has the value of one. A ratio is assets over liabilities.
The value of a ratio - of two numbers - is the value of the first divided by the second.
The Ratio of Earned Value to Planned Value is called the Schedule Performance Index. SPI = EV/PV
